The sides may have a shape that substantially conforms to the surface of the first part and the second part of the structure.

Description

BACKGROUND INFORMATION

1. Field
The present disclosure relates generally to manufacturing and, in particular, to manufacturing using adhesives. Still more particularly, the present disclosure relates to a method and apparatus for removing excess adhesive.
2. Background
Manufacturing an aircraft may be a complex and time consuming process. Manufacturing an aircraft may include, for example, without limitation, fabricating parts, assembling parts, installing systems, inspections, and other suitable operation for manufacturing the aircraft.
One operation performed in assembling parts may include connecting parts to each other to form structures for the aircraft. The connecting may be one or more of fastening, bonding, or other suitable operations. The bonding of parts to each other may be performed using an adhesive.
For example, without limitation, brackets may be bonded to various parts of an aircraft using an adhesive (or sealant). The bonding process for bonding a bracket to a panel may require the entire surface area of the bracket to be covered with the adhesive prior to installation. After the bracket is installed, some of the adhesive may squeeze out of the edges of the bracket onto the surface of the panel. This visual cue of the adhesive may indicate that a sufficient amount of adhesive was used to bond the bracket to the panel. This visual cue may be referred to as a “squeeze out.”
Leaving the squeeze out on the panel, bracket or both may be undesirable. Removing the squeeze out may be more time consuming to clean and messier than desired. Currently, a tool, such as a wood tongue depressor, may be used to remove some of the adhesive in the squeeze out. Thereafter, a towel with alcohol or some other solvent may be used to remove the remaining portions of the squeeze out from the surface of the panel. This current process may take more time and effort than desired.
Therefore, it would be desirable to have a method and apparatus that take into account at least some of the issues discussed above, as well as other possible issues.

SUMMARY

In one illustrative embodiment, an apparatus may comprise a base section. The base section may be configured to move along a surface of a first part and a second part of a structure. The base section may have sides that form a pocket. The sides may have a shape that substantially conforms to the surface of the first part and the second part of the structure.
In another illustrative embodiment, a method for removing a viscous material from a structure may be provided. A scoop may be moved along a surface of a first part and a second part in the structure. The scoop may have a base section with sides having a shape that substantially conforms to the surface of the first part and the second part of the structure. A portion of the viscous material may be guided on the surface of the structure into a pocket formed by the sides of the base section of the scoop as the scoop moves along the surface of the structure.
In yet another illustrative embodiment, an adhesive scoop may comprise an elongate member and a base section associated with an end of the elongate member. The base section may have an angle relative to the elongate member and sides that form a pocket. The sides may have a shape that substantially conforms to a surface of a first part and a second part of a structure. The sides may be configured to move along the surface of the first part and the second part of the structure. The sides may be configured to move along the structure and guide a viscous material on the surface of the structure into the pocket when the sides move along the first part and the second part of the structure. The sides may have an outer surface with a first contour configured to correspond to a shape of the surface of the portion of the structure. The sides may have an inner surface with a second contour configured to guide the viscous material into the pocket. The second contour may include a number of fillets configured to move the viscous material into the pocket. The sides may comprise a bottom side and a number of walls that extend from the bottom side to form the pocket. The number of walls may extend at an angle relative to the bottom side. The base section may have a leading edge located on the bottom side. The leading edge may be configured to contact the surface of the structure and the viscous material on the surface of the structure. A guide structure may be physically associated with a bottom side of the base section such that the leading edge maintains a desired angle when the guide structure and the leading edge contact the surface of the structure. The structure may be comprised of parts selected from at least one of a panel, a bracket, a stringer, a fuselage, a fuel tank, an airframe, a composite structure, or a skin panel.
In still another illustrative embodiment, a method may set an angle of a scoop. A guide structure physically associated with a bottom side of the scoop may be placed such that the angle for a leading edge is set to a desired angle when the guide structure and the leading edge contact the surface of the first part of the structure.
The features and functions can be achieved independently in various embodiments of the present disclosure or may be combined in yet other embodiments in which further details can be seen with reference to the following description and drawings.

DETAILED DESCRIPTION

The illustrative embodiments recognize and take into account one or more considerations. For example, the illustrative embodiments recognize and take into account that removing adhesive from a structure may take more time and effort than desired. The illustrative examples recognize and take into account that currently used methods for removing adhesive from a structure may not be as efficient as desired.
Thus, the illustrative embodiments provide a method and apparatus for removing a viscous material from a structure. In one illustrative example, viscous material may be removed using an apparatus. The apparatus may comprise an elongate member and a base section. The base section may be physically associated with an end of the elongate member in which the base section is configured to move along a surface of the structure and guide a viscous material on the surface of the structure into a pocket in the base section.
With reference to the figures, and in particular, with reference to FIG. 1, an illustration of a block diagram of a viscous material removal environment is depicted in accordance with an illustrative embodiment. As depicted, viscous material removal environment 100 may take various forms. For example, viscous material removal environment 100 may be manufacturing environment 102, maintenance environment 104, or some other suitable environment.
As depicted, viscous material 106 may be placed such that viscous material 106 applied to structure 108 is located between first part 110 and second part 112 in parts 113 that form structure 108. In these illustrative examples, parts 113 may be selected from at least one of a panel, a bracket, a fitting, a doubler, a stringer, a fuselage, a fuel tank, an airframe, a composite structure, or a skin panel.
As used herein, the phrase “at least one of,” when used with a list of items, means different combinations of one or more of the listed items may be used and only one of each item in the list may be needed. In other words, at least one of means any combination of items and number of items may be used from the list but not all of the items in the list are required. The item may be a particular object, thing, or a category.
For example, without limitation, “at least one of item A, item B, or item C” may include, item A, item A and item B, or item B. This example also may include item A, item B, and item C or item B and item C. Of course, any combinations of these items may be present. In other examples, “at least one of” may be, for example, without limitation, two of item A; one of item B; and ten of item C; four of item B and seven of item C; or other suitable combinations.
In the illustrative example, viscous material 106 may be a material having a consistency between a solid and a liquid. In the illustrative example, viscous material 106 may flow prior to being cured. As depicted, viscous material 106 may be at least one of adhesive 114, sealant 116, or some other suitable material.
For example, when viscous material 106 takes the form of adhesive 114, viscous material 106 may bond first part 110 and second part 112 at interface 118 to each other to form structure 108. Interface 118 may be where first part 110 and second part 112 contact each other.
When first part 110 and second part 112 are placed against each other with viscous material 106, viscous material 106 may be located between first part 110 and second part 112 at interface 118. Additionally, viscous material 106 also may be located on surface 120 of structure 108 in locations other than at interface 118 between first part 110 and second part 112. For example, this viscous material 106 may be located on surface 120 of at least one of first part 110 or second part 112. In the illustrative example, viscous material 106 on surface 120 of structure 108 at locations other than interface 118 may be referred to as “squeeze out” or “excess viscous material.”
As depicted, tool 122 may be used to remove viscous material 106 on surface 120 of structure 108. Tool 122 may take the form of scoop 124. When viscous material 106 takes the form of adhesive 114, scoop 124 may be an adhesive scoop.
In this illustrative example, scoop 124 may comprise elongate member 126 and base section 128. Elongate member 126 may take the form of handle 130 when scoop 124 is used by human operator 132. In other words, elongate member 126 may be handle 130 that is configured to be held by a hand of human operator 132. In some cases, elongate member 126 may be connected to robot 134 when elongate member 126 and base section 128 form end effector 136 for robot 134.
Base section 128 may be physically associated with elongate member 126. When one component is “physically associated” with another component, the association is a physical association in the depicted examples. For example, a first component, base section 128, may be considered to be physically associated with a second component, elongate member 126, by at least one of being secured to the second component, bonded to the second component, mounted to the second component, welded to the second component, fastened to the second component, or connected to the second component in some other suitable manner. The first component also may be connected to the second component using a third component. The first component may also be considered to be physically associated with the second component by being formed as part of the second component, extension of the second component, or both.
In this illustrative example, base section 128 may be configured to move along surface 120 of structure 108 and guide viscous material 106 on surface 120 of structure 108 into pocket 138 in base section 128. For example, base section 128 is configured to move along surface 120 of first part 110 and second part 112 of structure 108 in which base section 128 may have sides 140 that form pocket 138, in which sides 140 may have shape 141 that substantially conform to surface 120 of first part 110 and second part 112 of structure 108. Sides 140 may be configured to move along surface 120 of first part 110 and second part 112 of structure 108 and guide viscous material 106 on surface 120 of structure 108 into pocket 138 when sides 140 move along surface 120 of first part 110 and second part 112 of the structure 108. In the illustrative example, viscous material 106 may be present on surface 120 of at least one of first part 110 or second part 112.
In particular, sides 140 may include bottom side 142 and number of walls 144. In the illustrative example, number of walls 144 may extend from bottom side 142 to form pocket 138.
Further, sides 140 may be configured to move portion 146 of structure 108 and guide viscous material 106 on surface 120 of structure 108 into pocket 138 when sides 140 move along portion 146 of structure 108. In the illustrative example, viscous material 106 located in interface 118 between first part 110 and second part 112 is not considered to be located on surface 120 of structure 108.
In the illustrative example, sides 140 have an outer surface 148 with first contour 150 configured to substantially correspond to shape 152 of surface 120 of portion 146 of structure 108. First contour 150 may be substantially flat, curved, or some combination thereof. For example, if surface 120 is flat, first contour 150 also may be flat. If surface 120 has a curve, first contour 150 may have a curve that substantially corresponds to the curve of surface 120.
Additionally, sides 140 have inner surface 154 with second contour 156 configured to move viscous material 106 into pocket 138. In particular, second contour 156 may include number of fillets 158 configured to move viscous material 106 into pocket 138. In this illustrative example, a fillet in number of fillets 158 may be at least one of a curved surface or radius.
Further, base section 128 may have leading edge 160 in which leading edge 160 is configured to contact at least one of surface 120 of structure 108 and viscous material 106 on surface 120 of structure 108. More specifically, leading edge 160 may be located on bottom side 142 of base section 128. For example, leading edge 160 may contact surface 120 of first part 110.
In the illustrative example, number of walls 144 may extend at angle 162 relative to bottom side 142. Additionally, base section 128 may have angle 162 relative to elongate member 126. Angle 162 may be selected such that only leading edge 160 touches surface 120 without other parts of base section 128 touching surface 120 during use of scoop 124 to remove viscous material 106 from surface 120 of structure 108.
In the illustrative example, elongate member 126 and base section 128 may be comprised of a number of materials selected from at least one of polypropylene, polyethylene, a metal, polycarbonate, nylon, polytetrafluoroethylene, or other suitable materials. The number of materials may be the same or different materials between elongate member 126 and base section 128. As another illustrative example, the number of materials in base section 128 may be comprised of more than one type of material. As depicted, the number of materials may be selected such that at least one of elongate member 126 or base section 128 is rigid.
In the illustrative examples, scoop 124 may be manufactured in a number different ways. For example, scoop 124 may be manufactured using at least one of additive manufacturing processes, printing processes, injection molding processes, or other suitable processes.
In the illustrative example, scoop 124 may provide for the removal of viscous material 106 with a desired level of speed. Further, scoop 124 may provide human operator 132 with a desired ease-of-use when removing viscous material 106 from structure 108. Further, scoop 124 may be configured for quick and easy cleaning. In the illustrative example, scoop 124 may have a configuration that provides a finished or substantially finished seam at first part 110 and second part 112 on structure 108. The seam may be a bonded joint between first part 110 and second part 112.
Further, depending on the materials used, scoop 124 may be disposable. In other words, scoop 124 may be used for a particular period of time or any particular part.
The illustration of viscous material removal environment 100 in FIG. 1 is not meant to imply physical or architectural limitations to the manner in which an illustrative embodiment may be implemented. Other components in addition to or in place of the ones illustrated may be used. Some components may be unnecessary. Also, the blocks are presented to illustrate some functional components. One or more of these blocks may be combined, divided, or combined and divided into different blocks when implemented in an illustrative embodiment.
For example, in some illustrative examples, only a single wall may be present in number of walls 144. In other illustrative examples, elongate member 126 and base section 128 may be separate pieces connected to each other. In still other illustrative examples, viscous material 106 may comprise adhesive 114 and sealant 116.
Further, in some illustrative examples, a portion of viscous material 106 may be left on surface 120 of first part 110 and second part 112 of structure 108. For example, the portion of viscous material 106 may be left after the use of scoop 124 when viscous material 106 takes the form of sealant 116. In some cases, sealant 116 may only be applied to surface 120 and not between first part 110 and second part 112 at interface 118. The configuration of sides 140 may allow a desired portion of sealant 116 to remain on surface 120.
With reference next to FIG. 2, an illustration of a viscous material removal environment is depicted in accordance with an illustrative embodiment. As depicted, viscous material removal environment 200 is an example of a physical implementation of viscous material removal environment 100 shown in FIG. 1.
As depicted, structure 202 may be assembled on table 204. Structure 202 may be an example of a physical implementation of structure 108 in FIG. 1. In this particular example, structure 202 may include bracket 206 and panel 208. Bracket 206 and panel 208 may be examples of parts 113 in FIG. 1. For example, bracket 206 may be an example of a physical implementation for second part 112, and panel 208 may be an example of a physical implementation for first part 110 in FIG. 1. In this illustrative example, adhesive 210 may be used to bond bracket 206 and panel 208 to each other. In some illustrative examples, adhesive 210 may also function as a sealant.
Adhesive 210 may be located on surface 212 of structure 202. Surface 212 may be located on at least one of bracket 206 or panel 208. In this illustrative example, adhesive 210 on surface 212 may be excess adhesive and may be referred to as squeeze out.
As depicted, adhesive scoop 214 and adhesive scoop 216 may be used to remove adhesive 210 from surface 212 on structure 202. In this illustrative example, adhesive scoop 214 may be operated by human operator 218. Adhesive scoop 216 may be operated by robot 220. As depicted, robot 220 may be a robotic arm, crawler, or some other form of robot. In this type of implementation, adhesive scoop 216 may be end effector 222 for robot 220.
With reference next to FIG. 3, an illustration of an adhesive scoop is depicted in accordance with an illustrative embodiment. In this illustrative example, adhesive scoop 214 is an example of one implementation for scoop 124 in FIG. 1.
As depicted, adhesive scoop 214 may have elongate member 300 and base section 302. In this illustrative example, elongate member 300 may have handle 304 for use by human operator 218 in FIG. 3.
In this illustrative example, adhesive scoop 214 may have length 306. Elongate member 300 may have length 308 and base section 302 may have length 310. In this particular example, length 306 may be about 6.6 inches; length 308 may be about 5.6 inches; and length 310 may be about 1.0 inches. An enlarged view of base section 302 in section 312 is shown in FIG. 4 and described below with respect to FIG. 4.
In FIG. 4, an illustration of an enlarged view of a base section for an adhesive scoop is depicted in accordance with an illustrative embodiment. In this view of section 312 from FIG. 3, sides 400 in base section 302 are shown. Sides 400 may include bottom side 402, wall 404, and wall 406. As depicted, sides 400 may form pocket 408.
In this illustrative example, base section 302 has leading edge 410. In particular, leading edge 410 may be located on bottom side 402 in sides 400 on base section 302.
As depicted, elongate member 300 of adhesive scoop 214 also may have indicator 412 in the form of arrow 414. Arrow 414 may indicate that adhesive scoop 214 should be moved in the direction of arrow 416 by human operator 218 in FIG. 2.
In this view, sides 400 have outer surface 418 and inner surface 420. Outer surface 418 may have first contour 422, while inner surface 420 may have second contour 424. Of course, in other illustrative examples, indicator 412 may be located on base section 302.
First contour 422 of outer surface 418 of sides 400 may be configured to substantially correspond to a portion of structure 202 such as bracket 206. As can be seen in this example, surface 212 of structure 202 at bracket 206 is substantially planar.
In a similar fashion, first contour 422 of outer surface 418 at wall 404 may substantially correspond by being substantially planar. In this illustrative example, panel 208 may also be substantially planar. First contour 422 of outer surface 418 at bottom side 402 may substantially correspond to surface 212 at panel 208 by being substantially planar.
If surface 212 of structure 202 at bracket 206 has a curve, first contour 422 of outer surface 418 at wall 404 may also have a curve to substantially correspond to the curve of surface 212 at bracket 206, such that wall 404 may abut or touch surface 212 at bracket 206 without a gap or without an undesired gap.
In other words, number of walls 144 in FIG. 1 may have first contour 422 at outer surface 418 that allows for easy and quick removal of adhesive 210 from surface 212 through the selection or design of first contour 422. In other words, first contour 422 may be selected such that adhesive 210 may be removed with a desired amount of ease and speed as adhesive scoop 214 is moved along structure 202. In the illustrative examples, first contour 422 may be designed to remove adhesive 210 in a single pass operation.
As another illustrative example, front edge 442 of wall 404 and front edge 444 of wall 406 may taper. This taper in front edge 442 and front edge 444 may help guide adhesive to return into pocket 408 in this illustrative example.
Additionally, the configuration of leading edge 410 also may be selected to remove adhesive 210 with a desired amount of ease and speed as adhesive scoop 214 is moved along surface 212 of structure 202 by human operator 218.
As depicted, second contour 424 of inner surface 420 for sides 400 may be configured to aid in guiding a viscous material (not shown) on surface 212 of structure 202 into pocket 408 of base section 302 when sides 400 of base section 302 move along a portion of structure 202. In this example, the portion may be at least one of bracket 206 or panel 208.
Also, second contour 424 may be comprised of fillets. For example, fillet 426, fillet 428, fillet 430, fillet 432, fillet 434, fillet 436, fillet 438, and fillet 440 may be in second contour 424 for wall 404 in sides 400. Each of these fillets may be configured to aid in moving adhesive 210 into pocket 408. Additionally, these fillets also may be configured for cleaning of adhesive scoop 214. For example, these and other fillets in second contour 424 may be designed to reduce snagging of a towel or other device used to clean adhesive scoop 214, remove adhesive 210 from adhesive scoop 214, or both clean adhesive scoop 214 and remove adhesive 210 from adhesive scoop 214.
Turning next to FIG. 5, an illustration of an adhesive scoop is depicted in accordance with an illustrative embodiment. In this figure, a front view of adhesive scoop 214 is seen in the direction of lines 5-5 in FIG. 4 is shown.
With reference next to FIG. 6, another illustration of an adhesive scoop is depicted in accordance with an illustrative embodiment. As depicted in this figure, another front view of adhesive scoop 214 is seen in the direction of lines 6-6 in FIG. 4.
In this view, wall 404 may extend at angle 600 relative to bottom side 402. Wall 404 in this example may be substantially perpendicular to bottom side 402. Angle 600 may be about 90 degrees in this illustrative example. Of course, other angles may be selected depending on the particular implementation. The selection of the angles may be made such that outer surface 418 at wall 404 in sides 400 may touch bracket 206 (not shown) and outer surface 418 of leading edge 410 on bottom side 402 may touch panel 208 (not shown).
In FIG. 6, section 602 of adhesive 210 may be a film of adhesive 210 as compared to section 604 of adhesive 210. Section 602 may have at least one of an amount, shape, or other characteristic that is desired for section 604. In the illustrative examples, adhesive 210 in section 604 also may be removed using another device such as a cloth with a solvent (not shown). The removal may be performed easily with the use of adhesive scoop 214. A remaining portion of adhesive 210 in section 604 may have at least one of a desired amount or a desired shape. In some illustrative examples, it may be desirable to have at least one of a particular shape or amount of adhesive 210 remaining on surface 212 of structure 202. The amount, shape or both may be based on factors including at least one of aesthetics, sealing capability, specifications for the structure, or other suitable factors.
With reference next to FIG. 7, an illustration of a side view of an adhesive scoop is depicted in accordance with an illustrative embodiment. Adhesive scoop 214 is shown in a side view in the direction of lines 7-7 in FIG. 3.
In this view, base section 302 may have angle 700 relative to elongate member 300. Angle 700 may be selected such that leading edge 410 may contact surface 212 at panel 208 without other portions of outer surface 418 on bottom side 402 contacting panel 208.
The illustration of adhesive scoop 214 in FIGS. 2-7 is an example of a physical implementation for scoop 124 shown in block form in FIG. 1. Illustration of adhesive scoop 214 in FIGS. 2-7 is not meant to limit the manner in which other illustrative examples may be implemented. For example, indicator 412 may be omitted in other implementations. As another illustrative example, first contour 422 of outer surface 418 of sides 400 may be curved instead of substantially planar as shown in these examples.
In yet another illustrative example, guide structure 702 may be physically associated with bottom side 402 of base section 302 such that leading edge 410 contacts panel 208 in a desired manner to remove adhesive 210 on surface 212. Guide structure 702 may be shaped such that base section 302 has desired angle 704 when leading edge 410 contacts surface 212 of panel 208 and maintains angle 704 as adhesive 210 moves along surface 212. Angle 704 may be a predetermined angle of attack that causes removal of adhesive 210 from surface 212 in a desired manner.
In another illustrative example, length 310 of base section 302 may be increased in length. The length may be increased such that more adhesive, sealant, or both may be scooped up using adhesive scoop 214.
Turning now to FIGS. 8-10, an illustration of a process for removing a viscous material such as an adhesive from a structure is depicted in accordance with an illustrative embodiment. These figures illustrate removal of adhesive from a structure.
With reference to FIG. 8, an illustration of an adhesive scoop used to remove adhesive from a structure is depicted in accordance with an illustrative embodiment. In this depicted example, adhesive scoop 800 may be used to remove adhesive 802 from surface 804 of structure 806.
In this illustrative example, structure 806 may be formed from bonding bracket 808 to panel 810 with adhesive 802. As can be seen, adhesive 802 can be seen on surface 804 of bracket 808 and panel 810 at edge 812 of bracket 808.
In this example, adhesive scoop 800 may be moved in the direction of arrow 814 to remove adhesive 802 from surface 804 of structure 806. This removal also may be referred to as “scooping” in this illustrative example.
As depicted, indicator 816 in the form of arrow 818 may be present on adhesive scoop 800. Arrow 818 may indicate a direction of movement for using adhesive scoop 800.
In FIG. 9, an illustration of the removal of adhesive from the surface of a structure using an adhesive scoop is depicted in accordance with an illustrative embodiment. In this figure, adhesive scoop 800 has been moved along edge 812 of bracket 808. This movement may result in the removal of adhesive 802 located on surface 804 of structure 806 at edge 812 of bracket 808.
As can be seen in this illustrative example, adhesive 802 may be removed from surface 804 and guided into pocket 900 in base section 902 of adhesive scoop 800 as adhesive scoop 800 is moved in the direction of arrow 814. Adhesive scoop 800 is an example of one physical implementation for scoop 124 shown in block form in FIG. 1.
As depicted in this illustrative example, wall 904 in base section 902 is configured to remove adhesive 802 from edge 812 at bracket 808 and guide adhesive 802 into pocket 900. Additionally, leading edge 906 in base section 902 is configured to remove adhesive 802 from surface 804 of panel 810 and guide adhesive 802 into pocket 900. In this illustrative example, the guiding of adhesive 802 may result in adhesive 802 “rolling” into pocket 900.
In FIG. 10, another illustration of the removal of adhesive from the surface of a structure using an adhesive scoop is depicted in accordance with an illustrative embodiment. In this figure, adhesive scoop 800 has been moved further along structure 806 in the direction of arrow 814.
Any remaining amounts of adhesive 802 on surface 804 of structure 806 may be removed using another tool. The tool may be, for example, without limitation, a towel (not shown) with a solvent to remove any amounts of adhesive 802 that may still be on surface 804 of structure 806. With the use of adhesive scoop 800, the amount of time needed to remove adhesive 802 may be reduced as compared to currently used techniques. In addition, the ease of removing adhesive 802 also may be increased as compared to currently used techniques.
After adhesive 802 has been guided into pocket 900, adhesive scoop 800 may be cleaned. In these illustrative examples, adhesive scoop 800 may be configured for cleaning that may be as quick and easy as desired. This cleaning may be achieved through the configuration of surface 804 of adhesive scoop 800. Surface 804 may be curved such that a rag or other cleaning device does not catch on adhesive scoop 800 while cleaning adhesive scoop 800.
The illustrations of the different operations performed in FIGS. 8-10 are not meant to limit the manner in which operations may be performed to remove adhesive 802 from surface 804. For example, more than one adhesive scoop may be used at the same time to remove adhesive 802 from surface 804 of structure 806. In other illustrative examples, adhesive scoop 800 may also be used to remove sealant (not shown) from structure 806 in addition to or in place of adhesive 802.
The different components shown in FIGS. 2-10 may be combined with components in FIG. 1, used with components in FIG. 1, or a combination of the two. Additionally, some of the components in FIGS. 2-10 may be illustrative examples of how components shown in block form in FIG. 1 can be implemented as physical structures.
With reference now to FIG. 11, an illustration of a flowchart of a process for removing a viscous material from a structure is depicted in accordance with an illustrative embodiment. The process illustrated FIG. 11 may be implemented in viscous material removal environment 100 using scoop 124 in FIG. 1 to remove viscous material 106 of structure 108.
The process may begin by positioning scoop 124 relative to surface 120 of structure 108 (operation 1100). In operation 1100, leading edge 160 of the scoop may be placed on a first part of a structure. In operation 1100, the positioning may also include setting the angle of scoop 124 and in particular setting leading edge 160 relative to surface 120 of first part 110 to desired angle 704 while leading edge 160 contacts surface 120 of first part 110 using guide structure 702 that may be physically associated with bottom side 142 of base section 128 of scoop 124.
The process may then move scoop 124 along surface 120 of structure 108 (operation 1102). In this example, scoop 124 may include elongate member 126 and base section 128 that may be physically associated with an end of elongate member 126 in which base section 128 may be configured to move along surface 120 of structure 108. Viscous material 106 on surface 120 of structure 108 may be guided into pocket 138 in base section 128 of scoop 124 (operation 1104).
Any additional amounts of viscous material 106 may be removed from surface 120 of structure 108 after removal of viscous material 106 by adhesive scoop 214 (operation 1106). Operation 1106 may be performed using a tool such as a towel with a solvent. Viscous material 106 may be removed from pocket 138 of base section 128 of adhesive scoop 214 (operation 1108), with the process terminating thereafter. Removal of viscous material 106 from pocket 138 may be performed in a similar fashion to the removal of viscous material 106 in operation 1106.
